Show HN: An LLM-Powered PCB Schematic Checker (Major Update)

Traceformer.io is a web application that ingests KiCad projects or Altium netlists along with relevant datasheets, enabling LLM-based schematic review. The system is designed to identify datasheet-driven schematic issues that traditional ERC tools can't detect. Since our first launch (formerly as Netlist.io), we've made some big changes: - Full KiCad project parsing via an open-source plugin - Pass-through API pricing with a small platform fee - Automatic datasheet retrieval - ERC/DRC-style review UI - Revamped review workflow with selectable frontier models (GPT 5.2, Opus 4.5, and more) - Configurable review parameters (token limits, design rules, and parallel reviews) Additionally, we continue to offer a free plan which lets you evaluate a design before subscribing. We're looking forward to hearing your feedback!
